Synthesis of Ultrathin Indium Zinc Sulfide Nanosheets for Photocatalytic Hydrogen Production by Water Splitting
Zinc indium sulfide(ZnIn2S4)nanosheets were prepared by colloidal chemical method and characterized by atomic force microscopy(AFM),transmission electron microscopy(TEM)and X-ray diffraction(XRD).After the ligand exchange,the catalyst was used for visible light catalytic hydrogen production reaction,and the hydrogen production was tested by gas chromatograph to evaluate the catalyst performance.The results show that the ultra-thin ZnIn2S4 nanosheet with a thickness of only 1.8 nm is synthesized,and its hydrogen production rate is 600 μmol/(h·g),and it has good cyclic stability and high performance of photocatalytic hydrogen production by water splitting.It could provide the guideline for the design of photocatalysts in photocatalytic hydrogen evolution reaction.
